Title: Formation of two-color ohp original
Inventor: FUSHIDA AKIRA
IPC: G03G15/01
Filed: 1986-07-29
Abstract: PURPOSE:To easily obtain a bright two-color OHP image by forming a chromatic color toner image on a transparent film, then coating a solvent which swels a toner on the surface of the toner image. CONSTITUTION:The solvent which swells the toner is coated to part of the original for OHP obtd. by the chromatic color toner of a single color. The surface of the toner image in the coated part has a rugged shape and since light is eventually scattered or irregularly reflected by such surface, the light of the toner image part cannot arrive at the surface to be projected and the image part is blackish gray if such image is projected to the overhead projector OHP. The OHP original of the single color is thereby easily formed to the two-color OHP original. The solvent to swel the toner is exemplified by all kinds of solvents which swel the resins for the toner; for example, there are methanol, chloroform, tetrahydrofuran, toluene, acetone and ethanol. The solvent by being mixed with other solvents such as water may be used if the solvent dissolves the resin for the toner. All kinds of toners having light transparency are usable for the toner. The bright two-color OHP image is thus formed by the simple operation.
